Title: Gold alloys of exceptional yellow color and reversible hardness
Inventor: AGARWAL DWARIKA P
IPC: C22C5/02
Filed: 1992-10-29
Granted: 1997-09-09
Abstract: A unique hardenable gold based alloy, especially a 14 karat alloy containing gold, silver, copper, zinc, cobalt and an alternative alloy additionally containing iridium. The alloy has a fine grained structure, a lower hardness in the soft condition, a nice yellow color and a capability to be hardened to an exceptional hardness value. The alloy contains approximately 58.3% gold (Au), between about 10% to about 14% silver (Ag), between about 2.5% to about 3.0% zinc (Zn), between about 0.2% to about 1.0% cobalt (Co) and the balance of the alloy being copper (Cu) with the special provision that the ratio of the weight percent amounts of copper to, the sum of the silver and two (2) times the zinc amount, [Cu/(Ag+2Zn)], has a value of between about 1.3 to about 2.5. The copper to silver weight percent ratio [Cu/Ag] of between about 2.0 to about 3.8, in combination with the ratio of copper to, silver + 2 x zinc, [Cu/(Ag+2Zn)] results in a gold alloy with a heretofor unachievable combination of a most desirable yellow color and an exceptional degree of reversible hardness. The alloy may also contain a weight percent amount of between about 0.003 to about 0.03 iridium (Ir) which results in a gold alloy with the above characteristics but also provides for an alloy having a very fine grained structure.

Title: Method and apparatus for measuring pumping rod position and other aspects of a pumping system by use of an accelerometer
Inventor: WEST JERRY B
IPC: E21B47/00
Filed: 1992-12-09
Granted: 2000-02-15
Abstract: An oil well pumping unit has a walking beam which raises and lowers a rod connected to a downhole pump. To perform well analysis, it is desirable to know the position of the rod during the stroke. An accelerometer is mounted on the pumping system unit to move in conjunction with the rod. An output signal from the accelerometer is digitized and provided to a portable computer. The computer processes the digitized accelerometer signal to integrate it to first produce a velocity data set and second produce a position data set.      Operations are carried out to modify the signal and produce a position trace with stroke markers to indicate positions of the rod during its cyclical operation.
Patent CA-2085199-C (CA)
Inventor: DAY RICHARD M
IPC: B60L7/24
Filed: 1992-12-11
Granted: 1997-08-19
Abstract: The present invention features an improved technique for slowing and stopping a vehicle having an electric service motor, a mechanical parking brake, and a deadman's switch for engaging the mechanical brake.  The method of the invention improves the efficiency of the braking procedure.          The braking method initially determines if the deadman's switch is engaged.  If it is, then the electric service motor is plugged at a predetermined minimum plug rate until the vehicle slows to a specified velocity.  When the specified velocity is reached, the plugging operation is terminated.  The mechanical brake is then engaged to slow the vehicle to a halt.  When the vehicle comes to a halt, the parking brake remains engaged.  The invention also improves safety by increasing the controlled rate of plugging to a maximum value in the event that the deadman's switch is off.  Actual braking performance by plugging is compared with that of accepted rates of deceleration or plugging effort shown by armature current to verify operation of the service braking system.  In the event of inadequate service braking, such braking is terminated and the mechanical brake is applied.

IPC: A01M7/00
Filed: 1993-05-04
Granted: 1996-04-30
Abstract: A variable rate fertilizer spreading apparatus for spreading a precise amount of multiple types of fertilizers upon a field based upon a location in the field.   The system  comprises  a  controller  accessing  a  soil  map indicating the type of soil for each portion of the field, several  fertilizer maps storing the desired fertilizer level of each of the fertilizers stored in product bins on the tractor, and several status maps each indicating the current fertilizer level at various locations of the field to be fertilized.  By accessing the speed of the tractor via a speed indicator, and ascertaining the location of the tractor in the field via a position locator, such as an LORAN  or GPS  system,  an expert system determines  the dispensing rate of each of the fertilizers based on the various maps and the position and speed indicators such that the proper dispense rate of the fertilizers from bins is set to attain the desired level of fertilizers.   The expert system accesses standard and proprietary data tables and processes complex calculations taking into account the interaction effects of multiple fertilizers being dispensed upon a particular type of soil, as ascertained from the soil  map.    Thus,  each  portion  of  a  field  can  be characterized and fertilized such that the resulting level of each of the fertilizers matches the fertilizer maps after spreading fertilizer, where no predetermined path of vehicle is necessary.  The current fertilizer level map is updated after a dispensing pass to provide a real-time record.

Abstract: ABSTRACT OF THE DISCLOSURE         The invention relates to the field of protective covers for bags which may be carried by means of a harness or waist belt such as shoulder bags, fanny packs and the like. In order to provide additional protection against inclement weather, the bag comprises a pocket having a fastener  and  into  which  a  cover  of  flexible  water resistant material may be folded when the cover is stored. When additional protection for the bag is desired the pocket is opened and the cover unfolded from the pocket. The pocket contains the hinge joining the cover to the bag. The cover then extends around the bag to provide a water resistant covering extending over at least those sides of the bag which have openable flaps through which leakage may occur. The cover extends around but does not cover the harness so that the harness is still available for its intended use.

Abstract: A system for controlling initialization and self-test operations in a multiprocessor system (100) facilitates the use of central processing units (120, 132, 160) based around differing microprocessor types.  More specifically, the present invention involves storing configuration information, initialization self-test code, and boot code specific to each processor, memory module, or I/O circuit board in non-executable form in a non-volatile memory (123,129, 133, 161) on the respective circuit board, and storing the executable portion of the boot code needed by the initial boot processor in a centrally accessible non-volatile memory (152). Moreover, the present invention provides a system to automatically transfer default system initialization operations from a de-fault processor to a first alternative processor if the default processor fails, and to automatically transfer initialization operations to a second alternative processor if the first alternative processor fails, and so forth depending upon how many alternative proces-sors are installed in the multiprocessor system (100).

Title: Device and method for multi-phase radio-frequency ablation
Inventor: DESAI JAWAHAR M
IPC: A61N1/32
Filed: 1992-06-04
Granted: 2002-08-20
Abstract: Multi-phase RF ablation employing a two-dimensional or three-dimensional electrode array (501) products a multitude of currents paths on the surface of the ablation zone. This results in a uniform lesion with a size defined by the span of the electrode array. An orthogonal electrode catheter array suitable for cardiac ablation is used in conjunction with a two-phase RF power source to produce uniform square-shaped lesions of size 1,2 cm2. Lesions of larger size are created by successive adjacent placement of the square-shaped lesions. A temperature sensor (531) at the electrode tip allows monitoring of ablation tem-perature and regulation thereof to minimize the electrode tips from being fouled by coagulum.
